When me, or one of my friends, try to host a server to a fun coop game the other guys can't join the server. Just the host is able to play.
- Legacy ID
- Server Browser Steam
You need to forward several UDP ports to your PC:
2300 - 2305
(Google if you don't know how to do it in your router.) If it still doesn't work just enter your friend's IP via the "Remote" button next to the "Join" button.
Same issue. I tried port forwarding, but without luck. When click "new" in the server list and I switch from lan to internet in the creation menu it appears an error: "please ensure your game has internet accessibility via the following network ports: 2302, 2303".
